Abstract

The invention provides a rapid task planning method for a multi-source earth observation satellite. The rapid task planning method comprises the following steps: performing calculating to obtain satellite ephemeris data; establishing an Index in a space-time two-dimensional mode, establishing a data structure, and storing ephemeris data in a KEY-VALUE type database; Performing discontinuous ephemeris data screening in the candidate range, performing satellite visibility calculation, and performing calculation to obtain a point target visible window; Processing the region target by adopting a greedy snake algorithm to obtain a region target visible window, and generating a meta-task window according to the region target visible window; And optimizing and arranging the meta-task window by adopting a pluggable task planning optimization and evaluation method to obtain a relatively optimal planning scheme. According to the invention, rapid access of data can be ensured, unified mode high-speed processing of common satellites and agile satellites is realized, and high-quality task planning is realized in a multi-satellite and multi-task combined planning scene.

Description

technical field [0001] The invention belongs to the technical field of satellite measurement and relates to a fast task planning method for multi-source earth observation satellites. Background technique [0002] Satellite mission planning is the core business of satellite operation control. On the one hand, the various functions and algorithm research plans of satellite mission planning have made great progress after years of development. On the other hand, the number and types of satellites operating in orbit have increased sharply, including optical, SAR, electronic, video and other quasar satellites according to their load applications, and including traditional satellites and agile satellites according to their satellite capabilities. [0003] According to the business process, the satellite mission planning business is usually divided into three main components: satellite orbit calculation, visibility calculation (pre-planning), and satellite mission planning. These t...
